Green Screen after turning "monitor" off and on



So my computer recently started displaying a filled green screen after I turn the "monitor" off and on again. It doesn't seem to matter how long this takes, could be just a minute or a couple hours. I say "monitor" because my computer is hooked up to my tv via HDMI. The tv is a TCL Roku TV, if that's relevant.  needed a software update or something, but that doesn't appear to be the case. I built my computer myself, but I'm still pretty new to debugging problems and when I searched for this problem elsewhere, overclocking seemed to be a common issue but I don't even know what overclocking is, so I don't know if that's my problem. 

Possibly relevant information:

Video Card: SAPPHIRE NITRO+ Radeon RX 470 100407NT+4GOCL 4GB 256-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready

CPU: AMD - FX-8350 4.0GHz 8-Core Processor

Motherboard: Gigabyte - GA-970A-UD3P ATX AM3+ Motherboard

Memory: HyperX FURY 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 Desktop Memory Model HX318C10FBK2/16

Power Supply: EVGA SuperNOVA 850 G2 220-G2-0850-XR 80+ GOLD 850W Fully Modular EVGA ECO Mode 

Thanks in advance for any help!

Try to open the Control Panel and lower the refresh rate of the monitor, maybe it will work then.

This is what is called a handshaking issue between the HDMI devices. One or both of the devices is having problems communicating with the other. Maybe try a different HDMI cable, if you have one.

    • I'm new to this forum and my technical knowledge is extremely limited!

      1) Does anyone know if Microsoft are going to produce a Windows 11? I have found only conflicting information on the Internet.

      2) I have found lots of Windows 10 books on the Internet. Any recommendations for a good basic book on Windows 10?

      We pre-purchased and pre-installed the game Shadow of War on our gaming PC through Steam this week only to discover it would not launch when we clicked Play. I wanted to post our fix here in case anyone else searching the Web for clues to this needs help. 

      Tried uninstalling and reinstalling the game (all 100gigs worth). 

      Tried rolling back the nVidia graphics driver.

      Tried cursing (made me feel better but did not fix the issue). 

      Scanned and verified the game from within Steam

      Ran sfc /scannow from the command line to make sure Windows was OK.

      I ultimately realized the issue was with Visual C++ Redistributable

      I had multiple version installed. Some we very old. I removed them all and installed Visual C++ Redistributable for Visual Studio 2015 from here and that fixed it. https://www.microsoft.com/en-us/download/details.aspx?id=48145

      If anyone else had problems and found different solutions, let us know.
